Y3 Claims. 1

This invention relates tonew and useful improvements in lamp supportsfor use around automobiles and airplanes and similar locations.

An object of the invention is to provide a simple, eiiicient, strong,durable support vand lamp thereon which is available for use around, on,and beneath cars and planes and can be moved and adjusted to anyposition easily and in .the matter of a few seconds for illumination ofany work spot in connection with inspection and repair in garages,workshops and hangars.

Another object is to provide a support 1in which the lamp may beadjusted for wide variations in position without ever removing it exceptfor very exceptional locations and conditions, but which can be removedinstantly when it is desired to hold it in the hand of the workman forclose inspection of a work spot.

Further and more specic objects, features, and advantages will moreclearly appear from a consideration of the specification hereinafter setforth especially When taken in connection with the accompanying drawingswhich illustrate va present preferred form which the invention mayassume and which forms part of the specification.

In brief and general terms the device includes a base, a mast mountedthereon, preferably by means of a universal joint, said mast beingtelescopic within dened limits of movements, a lamp supported adjustablyon top of the mast preferably in a spring clip and connected to the topof the mast by means of a universal joint, and another spring clipmounted on the base also by means of a universal joint. The base memberis preferably movable on wheels and the mast and lamp may be adjusted ina matter of seconds to any desired position, above, around, or beneaththe work or the lamp may be instantly removed from either clip by a pullof the operators hand and as easily replaced therein.

The present preferred form which the invention may assume is illustratedin the drawings, of which,

Fig. 1 is a side elevation of the device in an elevated position;

Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1; and,

Fig. 3 is a side elevation, partly in section, of the vapor-proof lampemployed in the device.

Referring now merely to the specific constructiom illustrated by thepreferred form shown in the drawings, it is seen that there is a basemember preferably formed as a casting with several extending arms Imovably supported on wheels A-n extensible mast `is connected vat lits:lower' end by a ball-and-socket joint I-4 to the vbase member and isIformeel of two telescopic sections l5 and i3 adjustable by aset screwlll sothat-the length of the 4mast can be varied easily. vAlt the topofthe mast. is. Aanother balleand-socket joint `8 which supports anotherstrong. spring clip I9 adaptedV to receive-a porl'fiony of thehandlegrip 2l] of an inspection lamp 2l. l'lh-isvlamp is connected bycord-2,2 to' any suitable source of electrical power. A

'The lamp -is preferably lof -the vapor-proof type and .its novel.specic structure -is shown in Fig. 3 wherein the lampcasing 23 isat itssmall endl formed in a sealed .manner with the Iharuzl gri-p 20 whichalso houses the electrical connections and socket for the vbulb to beinserted therein. The casing is preferably of polished metal such asaluminum and parabolic in general shape, acting as a reector. The outerend of the casing is S-shaped to form a seat 24 for a gasket 25 ofring-like shape against which is placed a heavy plate of glass 2B. Theplate 26 is held in place by a metal clamping ring 21 secured to the endof the casing 23 by means of bolts 28. The casing is surrounded by awire guard cage formed of transverse wires 29 and longitudinal ribs 3Uwhich at one end are connected in any suitable manner to a clampingcollar 3l around the hand grip 2B and at the other end to the clampingring 21. The cage extends over the front of the lamp as shown at 3l soas to form a complete guard housing for the lamp to prevent contact ofthe lamp with objects which may break it and to avoid the operatorsperson being affected by the heat of the lamp,

As regards the several ball-and-socket joints employed, their use isextremely important but their specific structure is not part of theinvention since any suitable type of joint may be used. Preferably thesocket portions thereof are of the usual split type which can beadjusted to tighten or loosen the contact With the co-operating ballwhereby the parts may be moved freely but are held firmly enough tomaintain an adjusted position. Any suitable type of bulk (not shown) maybe employed but preferably strong bulbs of the dood-lamp type aregenerally employed.

Considering the practical every-day use of this device aroundautomobiles and airplanes where dangerous fumes and highly explosivefuels and volatile gases are always a menace, it is highly importantthat a vapor-proof device be employed and at the same time have itsupported so that it can be instantly available with a minimum of timeand effort either when the mechanic is working in a standing position orbeneath the plane or the car. That this device meets all theserequirements is self-evident from a consideration of the abovestructural description.

In the position shown in Fig. 1 the device is disposed for use when theworkman is standing working on the car or plane and the mast can beextended higher if desired by loosening the screw I1 and raising thesection I6 to the desired height. To make the lamp available for lowerWork it is merely necessary to grasp the mast in the hand and swing itdown to the required position around the ball joint I4. The lamp itselfcan |be swung around the ball joint I8 and assume any desired anglewhether it is high or low with respect to the ground.

When the workman is under the plane or the car, the mast is swung allthe way down so that it is nearly horizontal with the ground and thelamp adjusted in its ball joint to spot the point of work. If certainconditions require it, the lamp can be just pulled out of the clip I9and placed in the lower clip I3 when desired. This requires nounfastening of nuts or screws and can be achieved in a few seconds. Atany time, either in elevated or lowered condition, the device can bereadily and easily moved from place to place by reason of the wheels II.Also at any time the lamp may be quickly pulled out of the clips andmanipulated by the operator wherever he may be for more minuteinspections when called for. At all times the lamp is protected fromshock contact and the operator from the heat of the lamp, by reason ofthe wire guard.

While the invention has been described in detail and with respect to aspecic preferred form, it is not to Ibe limited to such details and formsince many changes and modiiications may be made in the inventionwithout departing from the spirit and scope of the invention in itsbroadest aspects. Hence it is desired to cover any and all forms andmodications of the invention which may come within the language or scopeof any one or m-ore of the appended claims.

What I claim as my invention, is:

1. In a device of the class described, the combination of a base membermovable on wheels, a telescopic mast connected to the base by auniversal joint, and a lamp supported on the top of the mast by auniversal joint.

2. In a device of the `class described, the comzbination of a telescopicmast, ball-and-socket joints at the top and bottom of the mast, a basemember provided with wheels and connected to the bottom joint, a springclip associated with the top joint, a lamp disposed in said clip,another ball-and-socket joint disposed on said Ibase, and a secondspring clip disposed on said last mentioned joint to receive the lampwhen it is removed from the first clip.

3. In a device of the class described, the combination of a telescopicmast, ball-and-socket joints at the top and bottom of the mast, a basemember provided with wheels and connected to the bottom joint, a springclip associated with the top joint, and a lamp disposed in said clip.
